Stochastic magnetic tunnel junctions can be used to create energy-efficient neural networks with confidence estimations. Feedforward neural networks can adapt to a wide variety of data analysis tasks and could help tackle the increasing volume and complexity of data being generated in the world. However, the energy cost associated with training these networks is high, owing to the memory wall associated with digital computation based on traditional von Neumann architectures1.

arising from T. Benkel et al. Nature Communications https://doi.org/10.1038/s41467-022-34765-w (2022)The introduction of β-adrenergic receptor blockers, “β-blockers”, as a treatment for heart failure decades ago was a major advance in cardiovascular medicine1,2,3,4. Moreover, it has been clear for a number of years that some β-blockers with “intrinsic sympathomimetic activity” (ISA) due to weak partial agonist activity mediated through G protein stimulation did not share this salutary effect5,6.

It was the best of times, it was the worst of times, it was the age with SDN Layer 3 gateways between sites, it was the age of no Layer 2 connectivity, it was the epoch of a clunky policy management system, it was the season of Darkness – I never actually read “A Tale of Two Cities” as you can tell.

Digital technology has what you could call a real estate problem. Hyperscale data centers now regularly exceed 100,000 square feet in size. Cloud service providers plan to build 50 to 100 edge data centers a year and distributed applications like ChatGPT are further fueling a growth of data traffic between facilities.
